About this game

Lead humanity from its infantile cradle to supreme solar dominance in Solar Nations 2, the grand strategy game where the Solar System becomes an intricate battlefield.

Build colonies on distant worlds, develop revolutionary technologies, and decide whether humanity will unite among the stars… or destroy itself in nuclear fire.

LEAD HUMANITY INTO SPACE

The nine planets of Sol are waiting to be conquered. Each one offers unique advantages, dangers, and strategic possibilities:

Mercury offers the closest access to the Sun.

Venus presents a high-risk, high-reward terraforming gambit.

Earth is rich in population and industry, but divided by old rivalries.

Mars boasts valuable resources and proximity to the Asteroid Belt.

Jupiter’s moons each provide unique opportunities for colonization and conflict.

Saturn holds a wealth of rare resources waiting to be discovered.

The Ice Giants present strange research opportunities at the edge of civilization.

The Kuiper Belt is a gateway to the unknown.

And beyond Neptune, the ninth world waits.

DETAIL WITHOUT TEDIUM

Solar Nations 2 allows great breadth and depth at once. 

In war, you command vast space fleets to conquer the planets, while also intricately customizing each vessel to fit a role of your choosing. 

In peace, you carefully navigate the political intrigues of an interplanetary society, while constructing great projects which will stand as testimonies of your greatness to future generations.

WAR OF THE FUTURE, FOR THE FUTURE

The civilizations of mankind are not divided by borders alone. They are divided by worldviews, ambitions, myths, fears, and rival visions of what humanity should become.

Every nation believes it has a unique claim on the future. Every ideology carries its own sense of righteousness. As mankind spreads beyond Earth, these old struggles do not disappear, instead they expand across the void itself: becoming greater in some ways and in others remaining the same.

Combine armies, aircraft, ships, spacecraft, and strategic weapons into an unstoppable war machine, with each force playing a distinct role in the great game of civilizations.

UNLIMITED POWER

In Solar Nations 2, you are the master of your nation's destiny. Everything which happens within your borders is something you preside over - there is no need to rely on AI help. Each mechanic is simple enough to understand while also offering strategic depth to ensure there is a wide variation of choices, where there isn't always a best solution.

YOUR OWN WORLD

Create alternate histories, future scenarios, custom nations, borders, flags, populations, and political setups with the built-in scenario editor. Share your creations through Steam Workshop, download community scenarios, and reshape the Solar System alone or with friends.

    Experimental 0.19

    Hello everyone, the experimental branch has some new features. Here is what they are:OrganizationsGeneral ChangesNon-alliance organizations no longer call all their members into wars.Economic Unions now allow you to build on allies' territories, and export/import resources from them for freeMilitary alliances now allow you to recruit units in allied territoryGermany can build buildings in any EU member state.HegemonyNew type of organization which allows you to puppet people within it. Hegemonies confer the benefits of military alliances and economic unions, with the added bonus that your new "allies" can't leave, and have to pay you some tributes.AI won't join hegemonies voluntarily, so the only way to get people in them is to force them to join through war, or release a country.Anyone besides China inside this organization is effectively a puppet state.Colonial NationsYou can now release your space colonies as colonial nations, but you don't have to, however like any released nation they automatically join all your organizations, so that will allow you to still gain many of the benefits of a colony. Font ExperimentationBehind the scenes, I am working on UI mockups and such for a big UI aesthetic change. Does this font look better than the last one? Leave a comment with what you think.
